University of Florida professor Sanjay Shukla recently tested taller, narrower compacted-soil rows for vegetable production. He planted rows 10-12 inches high and one and a half to two feet across. Instead of needing two drip lines to irrigate, these rows required only one. In addition, they needed less plastic mulch covering. Not only did the tall, narrow rows grow the same amount of vegetables, but they also retained more fertilizers, used less water, and used 50% less fumigation. Shukla estimates the revamped rows could save farmers $100 to $300 an acre.
